Images from scanned slides

These slides are about 40 years old or more and I have just started scanning the ones I like into the computer. The scanner I have is an Epson V500 and is supposed to remove dust and scratches from the slides but so far I have not had good luck with it, however I am still learning the system. I need to give each slide a good cleaning I think and then scan them. Eventually I will load them on DVDs for archival images.
